I found another OZ that have 6 pins in each side. Is an OZ815ln. I google it and i see that is and dc-dc or an PWM. Is the only 24 pins chip that i found.

U are right Jaro. I have another OZ8291 like of that in picture. i see another in back of board and i foun a new OZ. I found OZ8033GN. Its is close to a big chip ITE8500. This ITE are a Super IO?

same of that OZ.... is the switching chip? In that schematic how can i see witch is the switching?

Can u read now?

Another tips?
